8 Claims.

My present invention relates to a sad iron construction, particularly with respect to a simple and inexpensive means for connecting a shell to a baille plate of the iron.

A further object is to provide such connecting element with hooked notch and lug means of engagement with the baffle plate so that after the baille plate is secured in position on the sole plate and covering the heating element countersunk in the sole plate, the connecting element ance for a temperature indicator depending from the shell of the iron or for a thermostat adjusting screw extending down to a thermostat countersunk in a socket of the sole plate.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth,

pointed out in my claims and illustrated in the I accompanying drawings. is susceptible of a variety of embodiments, it is unnecessary to fully describe more than one in order to give a full understanding of the invention both from its structural and functional standpoints. Accordingly, I have illustrated a preferred and desirable embodiment of the invention in the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view through a sad iron showing my invention applied thereto. -a connecting element of the invention being shown in side elevation;

Figure 2 is a horizontal sectional view on the line 2-2 of Figure 1 showing a plan view of the sole plate and the baille plate mounted thereon;

Figure 3 is a sectional view on the line 3-3 of Figure 1;

Figure 4 is a perspective view of a connecting element of my structure as viewed from the bottom;

Figure 5 is a sectional view similar to Figure 1, showing a slightly modified connecting element;

Figure v6 is a sectional view on the line 6-6 of Figure 5, and

Figure 'I isa perspective view of the connecting element of Figure 5.and the portion of a 55 Although the invention baille plate with which it, in the form of connecting element shown in Figure 4, cooperates. On the accompanying drawings, I have used the reference numeral I to indicate a sole plate and I2 a heating elementcountersunk therein. A baille plate I3 is secured to the sole plate I0 as by screws or headed pins I4 pressed into openings I of the sole plate. The baille plate I3 retains the heating element I2 in position and refleets heat therefrom toward the lower surface of the sole plate I0. The baiiie plate I3 has a pair of. upstanding flanges I6 and I1 which are perhaps best shown in Figure 7. The flange I6 has a pair of notches I8 which are hooked, the hook membersv being indicated at I9. Similarly, the flange I1 has a notch hooked as at 2 I.

A connecting element C is adapted to coact with the hooked notches I3 and 20. y'Iwo of the connecting elements C and C are illustrated in Figure 4 and Figure 7, respectively. Each connecting element has a web 22 and a pair of flanges 23 and 24. The flange 23 is provided with a pair of outstanding lugs 25, while the flange 24 is provided with a single outstanding lug 26. Each web 22 is provided with a pair of threaded openings 2l and with a central opening (28 for they connecting member C and 28* for the connecting member C') The opening 28 is adapted to provide clearance for a temperature indicator 29, as shown in Figure 1, while the threaded openings 2l of the connecting vmember C are adapted to receive 'hold-down screws 30 for a shell 3| of the sad iron. The screws 30 may also retain handle supportingstraps 32 of a handle 33 in position.

During assembly of the connecting member C, the lugs and 26 are introduced in a rearward direction into the slots I8 and 20 which are open at their forward ends. The connecting member is then pushed rearwardly as far as it will go and when it is then lifted the lugs 25 and 26 assume a position behind the hooks I9 and 2i so that insertion of the hold-down scerws will retain the connecting member/in its 4raised position, as shown in Figure Land it cannot there- `after shift forwardly with respect to the sole llower edge contacting the upper surface of the sole plate.

The central opening 28' of the connecting ing screw 34, as shown in Figure .5. The thermostat itself is indicated generally by the reference character T and is countersunk in a socket'35 of the sole plate l0. After the connecting member C is associated with the hooked notches I8 and 2U, the adjusting screw 341s inserted. Thereafter, hold-down screws are screwed into the openings 21 for holding the shell 3| inposition, as illustrated in Figure 5. `Thereafter a knob 36 may vbe mounted on the thermostat adjusting screw 34 for .changing the adjustment thereof.

From the foregoing description, it will be obvious that I have provided a simply constructed connecting element for a sad iron shell with respect rto a baille plate of the sad iron. The connecting element may be readily associated with the baille plate without the use of screws or other connecting elements and the hold-down screws for the shell of the iron, when inserted, serve the purpose of holding theconnecting element against dislocation from its assembled position. v

Some changes may be made in the construction and arrangement of the parts of my device y Without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of Structure or use of mechanical equivalents which may `be reasonably included Within their scope without sacrificing any of the advantages thereof.
